The expiration date is set by the manufacturer assuming reasonably normal
storage conditions will be used.  It takes into account oxidation,
rancidity, changes in texture, deterioration of flavors, migration of
moisture, and to a limited extent microbiological problems.  Usually, the
latter are relevant only for canned or "wet"-type products, particularly if
they are non-sterile (e.g., milk).  Microbiological methodology is mostly
irrelevant in this scheme of things.
